(Ahem). We get it that you absolutely hate Konstantinova, but please keep some perspective and be factual.
Firstly -- Russia only needs the top 2 skaters to have a combined placement of 13 or less to keep the 3 spots. Trusova and Kostornaia are almost guaranteed to do that. Even last year, Zagitova + Konstantinova were 1+ 6 = 7 to get the 3 spots -- if Konstantinova hadn't existed, Zagitova + Tsurskaya 1 + 10 = 11 would still retain 3 spots.
Secondly -- This is insulting to Tarakanova as well. For all you know, she could place a resounding 3rd and make it impossible to send anyone else to JW.
Thirdly -- We probably needn't worry too much about Konstantinova being anointed into 3rd at JNats when the Junior version of her SP has not favoured her due to the required 3Lz single jump. The shift from 3Lz + 3T to 3F + 3T and backloading the combo (vs. a front-loaded 3Z3T being her previous norm) both contributed to the errors that cost her a 2nd JGP spot. So, this is the most likely comp where Tarakanova and / or Gubanova can beat her as she is the least likely of those 3 to be clean in the SP.
Would I root for Konstantinova to go to JW this year? No, and IMO she should withdraw from JNats since she is well in the way to qualify for Senior GP next season and already has enough results from Sr Nats + CS to make a case for 2 GP spots. But at the same time, let's not engage in unnecessarily vindictive speculation.
